This paper introduces a "continuous logic" constructed as a weighted sum of fuzzy AND and OR logics, called fuzzy squared. In order to provide adaptability to it, a parameter must be selected. A network model and a modified genetic algorithm are considered to meet the fuzzy squared logic needs. Simulations demonstrate that this logic can learn the behavior of a simple logic as well as of nonlinear control systems.

A complex first order system (CFOS), which has been defined mathematically and realized numerically in computers, is found to be realized by electronic circuit. The circuit is similar to the well known analog computer circuit for solution of second order equation, but not the same. The CFOS circuit can be used as a band pass filter. A vowel recognition system is constructed using CFOS filter bank and transputer. To construct a real time, module structured system, transputer's ability is used effectively.

This paper deals with the robust two-degree-of-freedom multivariable control system using H/sub /spl infin// optimization method which can achieve the robust stability and the robust performance property simultaneously. The feedback controller is designed using H/sub /spl infin// optimization method for mixed sensitivity function. The feedforward controller is designed using H/sub 2/ optimization method to minimize the error of both the transfer function of the optimal model and the overall transfer function. The feedback controller can obtain the robust stability property. The feedforward controller can obtain the robust performance property under modelling error. The robust two-degree-of-freedom multivariable control system is applied to the nonlinear multivariable boiler-turbine system. The boiler turbine system is analyzed at various operation points. The validity of the proposed method is verified in comparison with the LQG/LTR design method.

In this paper, we compare the 1-out-of-N representation scheme with three distributed ones, namely binary, Gray, and simple-sum. We put the emphasis on the training time, learning accuracy, and generalization capability. In order to evaluate the performance of these schemes, three multilayer neural networks (multilayer perceptron, multilayer quadratic perceptron, and multi-sieving network) are used to learn the vowel recognition and image segmentation problems.

A new concept of the degree of creditability of parameter value variations (DCPV factor) is proposed in this paper to solve problem that on-line monitoring and failure diagnosis of rolling element bearings are affected by monitoring parameter value variations caused by the intrusive vibration signals. Using the factor of the degree of creditability and the basic principle of expert systems, an on-line monitoring and diagnostic method of rolling element bearings with AI is developed. The technique enhances traditional vibration analysis and provides a means of automating the monitoring and diagnosis of a vibrating device.

A hierarchically structured classifier system (HCS) has been proposed by Lingyan and Jonathan (1991). The HCS uses structural ties to solve some of the classifier systems instability problems. In HCS, classifiers are grouped into families by relations, and these relations can be the classifier chains or default hierarchies. For large search and solution space problem, the performance of HCS with multiple level is better than ordinary HCS. In this paper, we propose the multiple HCS (mHCS) as an extension of HCS.

Linear parametric circuits are circuits whose dynamics are governed by linear differential equations having at least one time-varying coefficient. Under certain conditions, oscillations are induced in such circuits. During the oscillation, if variations in the erstwhile constant parameters of the circuit is made to depend on some external causes, then the oscillation voltage will experience modulation. By appropriate demodulation of the oscillation voltage, changes due to the external cause are transduced to obtain the desired signals for measurement, control or other purposes.

An inverter is designed and implemented, that applies pulse frequency modulation(PFM) in order to shape a constant DC voltage into an AC voltage with controllable magnitude and frequency. The authors investigated the effect of different parameters on the harmonic content of the generated PFM pattern, such as the effect of the ratio of carrier to reference frequency, modulation depth and pulse width using a software program constructed to simulate PFM patterns and calculate the corresponding harmonic content. According to these investigations an appropriate decision is taken about the suitable parameters of the PFM applied to the inverter.

A shear-type piezoelectric sensor is used for sensing both force and force derivative signals. Compared to a conventional multilayer-type piezoelectric cell, it has advantages of simple structure, low drive voltage and light weight. The proposed sensor is used for contact force control of an one-degree of freedom robot manipulator, and the effectiveness of force derivative feedback control is demonstrated through experimental results. A comparison is made with results obtained using strain gauge force sensor.

This paper shows that a PZT acoustic emission sensor is suitable, as one of the novel nonintrusive methods, for mass flow measurement of moved bed gravity flow in a stand pipe of the new high calorie gasifier or DRI process. This sensing signal is suitable for the process at 2/spl sim/:48 cm/s. The accuracy is below /spl plusmn/1.6% FS for 40.0/48.5 /spl phi/ pipe without band-pass filter. The band-pass filter is suitable for 75 kHz in 20.1/27.3 /spl phi/ and 40.0/48.5 of steel stand pipe with 1.8 /spl phi/ 1.5 kg/l silica pellets. It is able to delete inverse response of moved bed gravity flow. The frequency of red bean was 36 kHz in 20.1/27.3 /spl phi/ pipe.
